Etymology — The Origins of English Words

From Latin mīllēnārius.

From notion + -al.

From prophesy + -er.

From job + -er.

Borrowed from Latin ostentātus, perfect passive participle of ostentō (see -ate (verb-forming suffix)), intensive from ostendō. Doublet of ostent.

From mock + -er.

Probably a blend of irrespective + regardless. The word may also be analysed as ir- + regardless, as it is possible that the prefix ir- was added to amplify the negative in regardless just as plain negatives often did at the time the word came into use (and still do in dialects).

From misreckon + -ing.

From Middle English impregnacioun, from Old French impregnacion, in turn from Late Latin impregnatio.

Borrowed from German Plankter, from Koine Greek πλαγκτήρ (planktḗr, “wanderer; one who leads another astray, beguiler”), modelled after German Plankton (“plankton”). Πλαγκτήρ (Planktḗr) is derived from Ancient Greek πλάζομαι (plázomai) (the mediopassive of πλᾰ́ζω (plắzō, “to turn away from (something); to roam, wander”)) + -τήρ (-tḗr, suffix forming masculine agent nouns from verbs). By surface analysis, plankt- + -er.

From Middle English puissaunt, from Middle French puissant, poissant, Anglo-Norman puissant, Old French pussant, et al., present participle of pooir (“to be able”), ultimately from Latin posse (“be able”).

From hat + -ful.

Probably an affectionate alteration of mama or reduplication of maw (“mother”).

Late Middle English (in the sense “cutting, penetrating”), borrowed from Medieval Latin incīsīvus, from incīdō (“to cut in, cut through”) + -īvus (“-ive”, adjectival suffix). Compare Middle French incisif.

From Middle English *pleyhous, possibly continuing Old English pleġhūs (“playhouse, theatre”). By surface analysis, play + house. Compare Dutch speelhuis, German Spielhaus.

From French marauder, derivative of maraud (“rogue, vagabond”), from Middle French maraud (“rascal”), from Old French *marault (“beggar, vagabond”), from marir, marrir (“to trouble, stray, lose ones way, be lost”), from Frankish *marʀijan (“to neglect, hinder”), from Proto-Germanic *marzijaną (“to neglect, hinder, spoil”), from Proto-Indo-European *mers- (“to trouble, confuse, ignore, forget”), + Old French suffix -ault, -aud. Cognate with Old High German marrjan, marren (“to obstruct, hinder”), Old Saxon merrian (“to hinder, waste”), Gothic 𐌼𐌰𐍂𐌶𐌾𐌰𐌽 (marzjan, “to offend”). Related to mar.
